HMS Marlin (Yellow)

When this hits a hero, destroy the top card of their deck.

High Tide - If there are 2 or more blue cards in your pitch zone, this gets +1

and overpower.

HMS Marlin triggers when it hits a hero. You will destroy the top card of that hero’s deck when the triggered effect resolves.
Destroying the top card of that hero’s deck will not trigger any “when this is destroyed,…” effects unless it is specified by the ability’s triggering condition.
Destroying the top card of that hero’s deck will not satisfy any condition nor trigger any effects that look at whether you’ve destroyed an object you control (e.g. Merciful Retribution, Ratchet Up) as you do not control the cards in your deck.
High Tide checks your pitch zone constantly, not just when it attacks. If the condition is met after the attack is made, it will get the effect.

High Tide - – If there are 2 or more blue cards in your pitch zone, [EFFECT].

High Tide is a label keyword
High Tide’s continuous effect is constantly checking if there are 2 or more blue cards in your pitch zone.
Unless otherwise stated, High Tide is not functional on cards while defending.

Overpower - The defending hero can’t defend this with more than one action card.

Overpower is a static ability that generates a continuous effect.
A player can not declare more than one defending action card against an attack with overpower.
Overpower does not prevent additional action cards being added as defending cards through effects (e.g. Amulet of Havencall).
